What alternative theory exists regarding the structure of Jupiter's core materials?
Answer
The core material may have diffused or smeared out into the metallic hydrogen layer.
One theory suggests that due to intense pressure and heat, the material comprising the core (rock, metal, and ices) may have diffused or smeared into the surrounding metallic hydrogen layer, meaning a distinct, discrete solid core might not exist.
